The

consists

of
a

tank

unit

located
in
the

fuel
tank

and
fuel

gauge
The
tank

unit

detects
fuel
level

with
its

float

converts
fuel
level
varia

tion
to
a
resistance

of
slide
resistor

installed

on
the
float
base
and

thus

controls

current

flowing
to
the
fuel

gauge

BE16
The
water

temperature
gauge
con

sists
of
a

gauge
and
thermal
transmit

ter
located
in
the

engine
block
The

thermal
transmitter
is

equipped
with

a

thermistor
element

which
converts

cooling
water

temperature
variation

to

a
resistance
and
thus
the
thermal

tr

t
c

rtrols
cUfTent
flowing
to

the

gauge

The

fuel

gauge
and

water

tempera

ture

gauge
are

provided
with
a
bi
metal

arm
and
heater
coil
When
the

ignition

switch
is

set
to
ON
current
flows
to

the
heat
coil
and
the
heat
coil
is

heated
With
this
heat
the
bi
metal

arm
is

bent
and
thus
the

pointer

connected
to
the
bi
metal

arm
is

oper

ated
The
characteristics

of
both

gauges
are
the

same

A
tolerance

may
occur
on
the

water

temperature
gauge
or
fuel

gauge
due
to

source

voltage
fluctuation
The

voltage

regulator
is
used
to

supply
a

constant

voltage
so
that

the
water

temperature

gauge
and
fuel

gauge
operate
correctly

The

operating
part
of
the

regulator

consists
of
a
bi

metal

arm
and

a
heater

coil
When
the

ignition
switch
is

turned
on
the
bi
metal

arm
is
heated

and
bent

by
the
coil

opening
the

contact

Consequently
current
to

the

coil
is

interrupted
As

the
bi
metal

cools
the

contact
closes
The

repeti

tion

of
this

operation

produces
a

pulsating
voltage
of
8
volts
which
is

applied
to
the

water

temperature
and

fuel

gauges

If
both
the
water

temperature

gauge
and
fuel

gauge
become

faulty
at

the

same
time
this

may
be
attributed

to

problem
in
the

voltage
